which is the best filter for removal of Gaussian noise between sobel and LOG filters

I have added a gaussian noise of 5 to 15 dB to my images for creating practical scenario. I have used sobel filter for finding gradient magnitude. in my point of view sobel is better option for removal of gaussian noise and LOG is better option for removal of impulse noise. is my statement is correct and how to justify it?

Hi

Sobel and LoG filters are used to find the edges in the image. To remove the Guassian noise, you can use the averaging filter. Also you can check the below question which is already answered in the community.
